No. 571,342 7 Claims. (Cl. 112-2173) ABSTRACT OF THE DISCLOSURE A stand for supporting a sewing machine or the like and a motor therefor comprising a work supporting top surface having a machine receiving opening therein and support means including a bracket having means to support said motor and 'a machine supporting plate adjustable on the bracket and extending under said opening and having a front portion supported by a front bar of the support means whereby the sewing machine and motor are mounted independently of the work supporting surface and are adjustable as a unit with respect thereto.

Heretofore st ands have been provided for sewing machines in which the sewing machine has been secured on the table top and a motor therefor disposed below the table top. This required a relatively heavy table top to support the sewing machine and the arrangement produced substantial objectionable noise and vibration. Also, it required separate mounting elements for the sewing machine for locating it in situations where the machine was required to be mounted flush, semi-depressed or above the table top and this in turn required a number of drive belts of different lengths for connecting the sewing machine to the motor, all of which made it necessary to have a large inventory of parts.

The present invention overcomes these difficulties by providing a unique structure in which the noise and vibration are reduced, a minimum inventory of parts is required and in which the sewing machine can be readily located as required with respect to the top surface of the table top.

This is accomplished by providing a hole in the table top through which the sewing machine projects and by adjustably mounting a sewing machine supporting plate on a motor bracket to receive and support the machine there on. With the sewing machine and motor in a fixed relation, they form a unitary assemblage separate from the table which can be adjusted as a unit to locate the sewing machine with respect to the top surface of the table.

A feature of the invention resides in the fact that the sewing machine and motor are rigidly supported independently of the table top and, therefore, the noise of vibration is greatly reduced and not present in the present construction. Also, since the table top does not support the motor, it is not subjected to severe vibrations and it can be made of thinner and lighter material.

Another feature of the invention resides in the fact that the sewing machine and motor have a fixed relation which can be adjusted as a unit with respect to the table top to provide the proper required position of the sewing machine with respect to the top surface of the table; thus the need for an inventory of mounting devices for each position and of separate belts for each position is eliminated.

Other features and advantages of the invention will be apparent from the specification and claims when considered in connection with the accompanying drawings in which:

FIGURE 1 is a top plan view, partly broken away, of the table.

FIG. 2 is a section taken along line 22 of FIG. 1 with a sewing machine positioned on the table.

FIG. 3 is a view taken along line 3-3 of FIG. 1.

FIG. 4 is a view taken along line 4-4 of FIG. 1.

As shown in the drawings, a table top is provided with a flat work supporting surface 11 surrounding an opening or hole 12 therein. The opening is large enough to receive a sewing machine 13 to be positioned in predetermined relation in said work supporting surface and has a portion 12a to enable ready access to the usual handwheel 13a of the sewing machine. The table top is supported by two pairs of legs 14, secured to end brackets 16, 17, in the illustrated form of the invention, mounted on an underside of the table top adjacent the ends thereof with the legs 14 at the back of the table and the legs 15 at the front of the table.

A transverse "bar having an out-of-round or square cross-section with flattened ends 20a extends between the legs 14 with the flat ends of the bar vertically and adjustably secured to the legs 14 by clamping bolts 21 passing through an elongate slot 22 (FIG. 3) in each of the legs.

A motor bracket 25 has a recess 26 to fit the bar 20 and is clamped thereto by a saddle bracket 27 in adjustable position therealong and held against rotation on said bar. An electrical drive motor 28 has a pair of mounting members 29, thereon. As shown in FIG. 2, the member 29 is pivoted to the bracket 25 by a pivot pin 31. The member 30 is connected by an adjust-able link 32 to a pivot pin 33 carried by the bracket to enable the position of the motor to be adjusted with respect to the bracket for the usual purposes of belt changing and belt tightening.

The bracket 25 is provided with an upper horizontal surface 25a on which is adjustably secured a sewing machine supporting plate 35 by means of clamping bolts 36. The plate 35 has an upper surface to which the sewing machine 13 is secured by means 37 (FIG. 2). The bracket 25 is adjusted longitudinally on the bar 20 so that the plate 35 projects under the opening 12 in the table top 11 to support the sewing machine 13 therein with final adjustments of the position of the sewing machine in the opening made by adjusting the plate on the bracket as permitted by the elongate slot means 36a, as shown in FIG. 1, through which the clamping bolt 36 passes.

The forward end of the plate 35 is supported on a second transverse bar 40, herein illustrated as being L- shaped, extending between the front legs 15. The bar is provided with flat end portions 41 which are adjustably clamped to the legs 15 by bolts 42 passing through vertical elongate slots 43 in the legs shown in FIG. 4.

It will be seen that when the sewing machine is fixedly secured to the bracket 25 carrying the motor 28 a unitary assemblage is provided which is supported by the bars 20 and 49 independently of any support by the table top so that vibration and the noise attendant thereto are not amplified by the table top and are greatly reduced. Also, since the table top is not required to support the sewing machine, a thinner top may be used if desired.

Since the sewing machine 13 is not mounted on the table top but is carried by the plate 35 rigidly secured to the motor bracket 25, it can be readily properly located so as to dispose the sewing machine in a position either flush, semi-depressed or above the work supporting surface of the table top, all without requiring any special fittings to produce this result. In accomplishing this, it is merely necessary to loosen the clamping bolts 21, 42 for the bars 20 and and adjust them in the vertical slots 22, 43 in the legs 14, 15, thus eliminating the necessity of having a wide inventory of mounting means for the sewing machines to obtain these results.

Also, with the sewing machine and motor forming a unitary assemblage, the drive shaft 13b of the sewing m'achine 13 and shaft 28:: of the motor are normally spaced a predetermined fixed distance apart in all adjusted positions of the sewing machine on the table so that a standard or single length belt 46 can be employed to drive the machine from the motor. This will reduce the inventory of different length belts which was necessary in the prior art to accommodate the various positions of the sewing machine.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
